Title: Aluminum nitride substrate having copper circuit
Inventor: TSUJIMURA YOSHIHIKO
IPC: C04B37/02
Filed: 1989-09-28
Abstract: PURPOSE:To improve the bondability with an Al nitride substrate by using a copper plate having a low oxygen content. CONSTITUTION:A copper plate and an Al nitride substrate are heated and bonded to each other and are integrally formed using an active metal, such as silver, copper, titanium, zirconium or the like, or mixed powder consisting of a compound containing these active metals as the cementing material of the copper plate with the substrate. Here, unless the oxygen content of the copper plate to be used is less than 50ppm, the bondability of the copper plate to a brazing metal is not sufficient. Therefore, it is necessary that the amount is desirably set at 30ppm or less. In a copper plate having an oxygen content of 100ppm, a part which is not bonded is generated. Moreover, in obtaining an Al nitride substrate having a copper circuit, a ratio of silver : copper = 60 to 80% : 20 to 40% is desirably adopted in a weight ratio as the mixing ratio of silver : copper powder.

Title: Automatic transaction device
Inventor: NAKAGAWA MASANAO
IPC: G06Q40/02
Filed: 1984-11-27
Abstract: PURPOSE:To inquire the cause of a circuit error precisely by reading out the contents of error detection which are stored in a subsystem at the restoration of the circuit from a main system and dumping the read result to an external storage medium. CONSTITUTION:When a circuit error is detected at the reception of a command or the transmission of the command to the main side, the sub-side transfers the contents of a normal area m1 as they are to an error storage area m2. When the circuit error is detected at the time of transmission/reception, the main side dumps the main side data related to the sub-system to a floppy disk 14. When the circuit is restored as the result of circuit restoration processing, an error contents acquisition command is sent to the sub-system and the contents of the area m2 are received from the sub-system and stored in a RAM area corresponding to the sub-system. If no circuit error is generated at the time of reception, the data received from the sub-system are dumped to the floppy disk 14. Thus, the cause of the circuit error can be precisely inquired and hardware for dumping the data to the memory of the sub-side can be omitted.

Title: Voltage propagation circuit
Inventor: UEKI ISAMU
IPC: H03F3/343
Filed: 1986-10-21
Abstract: PURPOSE:To improve linearity and to minimize power consumption by permitting a current mirror circuit to feed back a current generated by an input voltage to an input stage. CONSTITUTION:The titled circuit has a start-up circuit 1 which supplies a current enough to start transistors Q1 and Q2 operating and the following current mirror circuit 2. If inputs the collector current of the transistor Q2, into which the transistor Q1 and Q2 and a resistance R1 convert the input voltage VIN, inverts the polarity of the current, supplies a current to the emitter of the transistor Q1 and the base of the transistor Q2 from a one output terminal, and outputs the current to an output resistance R2 from the other output terminal. The rate of resistances R3-R5 in the current mirror circuit 2 determines the rate of a current mirror, and 1:1 holds in this case. Thus the relation between the input voltage VIN and an output voltage VOUT becomes linear, and the current of the start-up circuit 1 is minimal, thereby reducing power consumption dramatically.

Title: Spindle stock with hybrid bearing
Inventor: NAKAGAWA MASAO
IPC: F16C32/00
Filed: 1989-09-27
Abstract: PURPOSE:To obtain a spindle stock with a hybrid bearing, which enables us to carry out high precision machining in addition to high-speed and heavy load machining by using only one spindle stock, by giving a main bearing double structures, e.g. rolling bearing and static pressure bearing, and providing a switching means switching from the static pressure bearing to the rolling bearing. CONSTITUTION:When a main spindle 7 rotates at a low speed in accordance with a command from a controller 10, since frinctional resistance of a pre-loaded rolling bearing 5 greater than that of a static pressure bearing, an intermediate housing 4 rotates together with the spindle 7. When the spindle 7 rotates at this time, the rolling bearing 5 serves as a static pressure bearing. Next, when the rotating speed of the spindle 7 becomes a medium one according to a change of a command value from a controller 10, rotation is initiated between the housing 4 and the spindle 7, and a mixed bearing condition, or a combination of the rolling bearing 5 and static pressure bearing, appears. However, since a rotational difference between the housing 4 and the main spindle 7 is small, the rotation of the main spindle 7 is maintained basically under the action of the static pressure bearing. Next, when an electromagnetic disc brake 21 is applied by a programmed command in order to restrict the rotation of the housing 4, the spindle 7 is rotated on the rolling bearing 5. At this time, the temperature-regulated, pressure oil supplied static pressure pads 12a to 12c gives the bearing 5 a cooling effect, while it gives the spindle 7 a damping capacity against the vibration through the static pressure plane.

Filed: 1987-10-08
Abstract: PURPOSE:To reduce the production cost of a device and to miniaturize the device by providing an adjustment space to the fitting part for an objective which is positioned at the outermost side of a main body member. CONSTITUTION:The objective 16A at the top is fitted in a recessed part hole 42 as the fitting part formed at the tip surface part of the main body member 4. Then the internal diameter of this recessed part hole 42 is made larger than the external diameter of the objective 16A to form the adjustment space T.
